Log
返回所有已执行的查询。
log()
返回: [array] 包含所有已执行查询的数组。
此函数只有在初始化时设置了 `logging => true` 才会返回所有记录，否则默认只返回最后一条记录。
$database = new Medoo([
"type" => "mysql",
"host" => "localhost",
"database" => "name",
"username" => "your_username",
"password" => "your_password",
// 启用日志记录。
"logging" => true,
]);
$database->select("account", [
"user_name",
"email"
], [
"user_id[<]" => 20
]);
$database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com"
]);
var_dump($database->log());
// array(2) {
// [0]=> string(62) "SELECT "user_name","email" FROM "account" WHERE "user_id" < 20"
// [1]=> string(74) "INSERT INTO "account" ("user_name", "email") VALUES (\'foo\', \'foo@bar.com\')"
// }
// 如果初始化时 "logging" => false 或默认忽略，将只输出最后一条记录
// array(1) {
// [0]=> string(74) "INSERT INTO "account" ("user_name", "email") VALUES (\'foo\', \'foo@bar.com\')"
// }
